LAST-A-FOAM® R-9300 Continuous Insulation Block Series

Reliable, insulation blocks support heavy building and equipment loads

In cold-storage and industrial facilities, LAST-A-FOAM® R-9300 Structural Continuous Insulation construction blocks create an insulation envelope from the building roof to below ground. Combining their high-strength structural support with a thermal barrier stems energy losses at the slab, walls and roof. Architects, engineers and other design professionals use them to fulfill a full range of applications.

The Challenge

Develop a wood replacement product that supports heavy structural loads with minimal deflection while extending a building insulation envelope from the roof to the foundation.

Key requirements include the following:

Ensures minimal energy loss to cooler/warmer earth at the foundation

High compressive strength to support building and equipment loads

Creep resistant – resists distortion under load over time

Locks out moisture – closed-cell material does not absorb water

Chemically and biologically inert – will not rot or decompose

Does not promote steel corrosion

Does not attract or support insects or vermin

Will not release chemicals into surrounding soil

Compatible with grouts, adhesives and concrete

Contributes to LEED certification

Applications

Subgrade and ground level

General Plastics’ structural panel blocks connect wall insulation to the foundation perimeter insulation when placed beneath precast and tilt-up concrete walls to support wall loads. Similarly, connecting the perimeter foundation insulation to a building’s interior insulation through our Thermal Column-Bearing Blocks prevents cooled or heated interior air from escaping through the surrounding ground and vice versa.
